MuseScore lets you notate and compose music easily with your keyboard, your mouse, or a MIDI keyboard. You can print beautifully engraved sheet music or export it as PDF or PNG. You can play your score, transpose it, and save it as audio or MIDI file. MuseScore also supports MusicXML to let you share your composition with other scorewriters. MuseScore is often advertised as a cost effective alternative for Sibelius and Finale.

Echoart responds to or drops ICMP echo request
packets based on a pre-defined sequence, and
could be used to return crude ASCII art in
response to pings from a Cisco router. It works
by intercepting ICMP echo request packets and
consulting a pattern template to determine
whether or not to respond to a specific echo
request. It then uses libnet to inject responses
back into the network as necessary.

This is the full source release of the
"equalize_it" C=64 music disk, scripted in TKS and
powered by EQU, SidPlay2, SDL, libpng, zlib, and
OpenGL. "Equalize it" is a nostalgic journey
through 20 years of C=64 SID music featuring many
well known SID composers like Jeff, Martin Galway,
Rob Hubbard, Mitch'n'Dane, Reyn Ouwehand, Matt
Gray, and many more.

RealmForge is a .NET 3D game engine predecessor to
Visual3D.NET (www.visual3d.net), which is a
framework and toolset for the visual design and
development of 3D games, simulations, and
interactive environments using C#, .NET 2.0,
visual scripting, and the XNA Framework.

The Data Language (TDL) is an Interactive Data Language-compatible
incremental compiler. Like Matlab, it is intended for scientific data
processing and visualization. It has a FORTRAN-like syntax, supports
objects, and has powerful array operations.

JCGrid is a set of easy-to-use tools for
real-world grid-computing. It doesn't require any
file system sharing capability (such as NFS). It
allows you to easily split a CPU-intensive task
among several computers by using the JCGrid
framework. Any file required for completing the
task will be transferred by the framework. A cache
is used in order to minimize file transfers. You
can easily add or remove computers from the grid
at runtime without losing any work. Support for
POVRay is included as an example of use.

The Visual Component Framework is a cross platform
C++ application framework that offers a modern,
clean architecture. It is divided into three major
libraries. The FoundationKit provides services
such as file access, streams, threads,
synchronization primitives, and advanced RTTI
features. The GraphicsKit includes classes for
working with both image and vector graphics, and
has built in support for the Anti-Grain Graphics
library. The ApplicationKit provides GUI controls,
use of the Model-View-Control pattern, property
and component editors, undo/redo support,
drag-and-drop, clipboard services, application
resources, and UI metrics and policy managers.

FinchTV is a way to easily view and edit your DNA sequencer chromatogram data. It can display an entire trace in a scalable multi-pane view, and will also display quality values (when available). You can edit your base calls and save your data to a new chromatogram file for later use, select and copy sequence for use in other applications, and print your trace out to paper or a file. You also have the ability to search your sequence data using regular expressions or simple base queries, to view raw data from .ab1 files, and to reverse complement your sequence and traces.

The Torque Network Library is a robust,
secure, and easy-to-use cross-platform C++
networking API designed for high performance
simulations and games. It features a UDP-
based connection architecture with DoS
prevention functionality, different types of
data guarantee, bit stream compression,
server object replication and updating, and a
simple, highly space efficient RPC mechanism.
It includes a deterministic application
journaling replay function for eliminating hard
to find networking bugs.
